Predator-Prey Beetles Game
Summary: In this lesson, students play a simulated board game of Clerid Beetle vs Mountain Pine Beetle. This game and graphing activity is a fun way to represent the predator prey model showing how each population responds to the other.
After completing this activity, students will be able to understand:
Predators (species A) are animals that prey (hunt, kills, eats) other animals (species B). Species A will benefit by feeding on species B.
The Predator/Prey model aka Lotka-Volterra model is based on an equation that describes interactions between two (predator and a prey) species in an ecosystem.
The Predator/Prey model reveals that the population size of the predator oscillates with the population size of the prey creating.
When population numbers of the predator and prey are graphed over time the graph show:
o As prey population increases, this is followed by the predator population increasing.
o Prey numbers will decrease as predator numbers increase
o Predator numbers will decrease as prey numbers decrease
o Prey will then begin to increase and the cycle starts over
